The first step would be to check the wiring from the malfunctioning light all the way up to the connector. Make sure all the connections are reasonably clean and secure, and check for frayed wires. If everything looks good from there, I would begin to look at the tow vehicle wiring.
Check to make sure your connections are clean and secure. We have a few handy devices that could help you check all this. You could use a circuit tester like part # 40376 to check to see what connections are functional. We also have in-line trailer connector testers like part # I26 or #118147.
I have included a couple links to a page and a video that may be helpful to you.
